Be it known that 1, CHARLES H. MARTIN,

a citizen of the United States of America.

residing in the city of Springfield, county of Hainpden, and State of Massachusetts,

have invented certain new and useful Improvements in Automobile-Badiators, of which the following is a specification.

This invention relates to an improvement used with water cooled automobile engines.

An object of the invention to provide a radiator, the parts of which may be put together, taken apart, and replaced more conveniently than heretofore.

Another object of the invention is to provide improved means for connecting and supporting the radiating members (as tubes) with the upper and lower header members or manifolds. j

' Other objects of the invention will appear in the detailed description and annexed claims. I

The preferred form of my invention is shown in the accompanying drawings for the purpose of illustrating one .way in which the invention may be carried out.

In the drawings: Figure l is a front elevation of an automobile radiator egnhodying the invention with parts removed; Fi *2 is a composite longitudinal sectional view taken on the line 2-2 of Fig. 1, assuming the latter figure to be complete; Fig. 3 is a transverse sectional view of the radiator assembled and ready toreceive the header men'ibers; Fig. 4 is a detail sectional view similar to Fig. 3 with a header member shown in place; Fig. 5 is a partial sectional plan view of a modified form of the invention; Fig. 6 is a partial front elevation of the same; Fig. 7 is a fragmentary vertical section of the same modification.

In the form of the invention shown, the radiator comprises. in general, upper and lower header membersl and 2, and individual open-ended radiator pipes 10. communicating independently with each header member or manifold. the upper and lower header members and the manner of connecting and suporting the radiator pipes respectively thereto are the same. The construction and arrangement will be described with reference to the upper header member and this description will sufiice for both.

This upper header member 1 is a box-like in radiators and particularly to radiators The construction of "structure closed except for one side which open. The open side is provided around its edge'with an outwardly extending flange A plate 6 is constructed to fit over the open side of member 1 and extends to the edge of flange 3. lacl'ting 6 is placed between the plate and the flange 3. The open ended radiator pipes 10 pass through holes in plate 6 slightly larger than the pipes, and communicate with the interior of the header 1. These holes are countersunk on the entrance side to receive packing 12. The latter jammed tightly around the pipes and into the countersunk holes of the plate 6 by means of adjustable cross bars 14'. (ltwill he noticed that for convenience the, radiator pipes 10 are arranged in transverse sets of four and these sets are arrangia'l in a longitudinal series extending entirely across the radiator). This is best shown in Fig. 2 and one of the transverse sets is clearly shown in Fig. 4. Each'trossbar 14 (see Figs. and 4) is provided with (.OUIltGlSllDk holes (slightly larger than the pipes). to receive a transverse set of the pipes 10 and the pack ing 12 is seated in the countersunk spaces. suits 16 pass freely through opposite ends of each cross bar 1.4v and thread into opposite ei'lgcs. of the plate (i.- These bolts when tightened force the adjustable cross bar-1i. and thus packing 12, against the plate (3. Thus the packing 15 around each pipe 10 forms an effectual seal between the. pipe and plate 6. These bols 16 also fit loosely into holes in the flange 5 of the header 1 and the latter is secured to the plate (5 with the packing 7) therebctwecn by nuts, as Shown in Fi l. The threaded engagement of the bolts 16 with the plate 6 permits the pipes 10 to be entirely assembled in the plate 6 before the header 1 is placed in position. It should be particularly noted that the ends of pipes 10, since they pass through holes in cross bars lland plate (5 slightly larger than the diam eter of the pipes. are supported by theyicld ing packing 15. As the pipes are thus supported at he ends and nowhere else they are, cushioned against all. shocks. This I consider of especial importance in automobile radiator construction because it permits the use of readily removable units without the pipe connections being rendered lcaliy after use.

The construction and arrangement for "connecting one transverse set of pipes 10 With the header member 1, described in connection with Fig. 4. is identical for all sets of the longitudinal series indicated in Figs. 1 and Moreover, the pipes 10 are secured to the lower plate 9 and the flange t .5 of the lower header 2 is se ured to the plate 9 in a manner identi al with that already described.

The means for bracing and binding the assembled pipes into one strong unit will now be described. The flanged header members 1 and 2. and plates 6 and 9 me securely bound together at their opposite ends by the flanged bracing and support ing plates 7 and 8. These. supportingplates or side members are bolted toland through plates 6 and 9 and the header members. To provide for twisting strains, the centrally arranged and diagonally crossed bracing rods 20 are provided. the ends of which pass through opposite ends of flanges 3 and 4 and have takeup nuts thereon.

The n'iodifie'l form of the invention shown in Figs. 5, 6 and 7 will now be described. The general arrangement of this modified structure is identical with that previously described. The main point of ditference, however, lies in theprovision of .a single plate 20 secured in the manner described. y a 'relatively small number of bolts 21. to a plate 23, which latter corresponds to the plate 6 heretofore described. Thus the individual plates 14 are in this modification combined into a single element 20. In*this.connection it is to be noted that counter-sinking of the holes in the plates 6 and 14 is not absolutely necessary. I may, if I desire, omit this countersunk feature as shown in Figs. 5, 6, and 7, and employ simply' the flat surfaces of the plates 20 and 23 to sflueeze the packing 22 against the. pipes 10. The holes inthe plates '20 and 23 are larger than the. pipes 10 so that thelatter are resiliently supported hywthe packings 22. The. structure shown in Figs. 5, 6, and 7 is shown to illustrate one way in which my device. may be modified but it is to be understood that the preferred form of my invention is embodied in Figs. 1 to 4 inclusive.

It is to be noted that stuffing boxes, flanged joints. ground joints. and all the other similar devices commonly employed in radiators are not ne essary in my device. On the contrary the. joint between the pipes 55 l and the plates (3 and 9 is an extremely simple one. 'lhus. due to its simplicity. the structure 'is comparatively inexpensive to manufacture. Moreover. although the joint between the pipes and the plates 6 and is simple. it is very etlicient and entirely suitable for radiators. particularly where ordinary pressures are employed. Furthermore. the connection between the pipes and the plates is one which does not readily loosen, since the pipes are supported primarily by the pa king and only secondarily-by the plates (3 and Thus vibrations of the plates (3 and 9 are not readily transmitted to the pipes 10 through the yieldable packing l2, and due to this yicldable support the pipes do not become loosened and a water tight joint is maintained. (onstant attention to prevent leakage. is thereby rendered unnecessary with my radiator.

Another marked advantage of my structure lies in the fact that the tubes 10 may all be assembled in a rigid frame. comprising the members (3. 7. Pa. and 9. before the header members land 2 are put in place. Thus each individual joint is a cessible for inspection before the members 1 and :2 are applied. After the headers l and 2 have been applied and in event of a defective pipe 10 only onigroup comprising four pipes need be removed from the. radiator to I repair the defect. Assuming one pipe 10 to be defective, a pair of bolts 16 at the top and the corresponding pair at the bottom of the radiator are loosened. The plate 14 then drops freely away from the. plate (3 and the group of four pipes may thereafter be pushed downwardly so that their ends lie slightly within the lower header2. This action withdraws the upper ends of one set of pipes 10 and trees them from the top plate 5. after which they may be conveniently removed. A new pipe IO-may then quickly and easily replace the defective pipe and the group be again secured to the plates (3 and 9 by reversing the procedure just described.

Thus my radiator is arranged with a plurality of readily removable radiating units and each radiating pipe is resiliently supported to eliminate shocks and vibrations. It is rcmgnized that many modifications may be made in the structure herein described without departing from the scope of my invention which is defined in the appended claims.

\Vhat I claim is:

1. An automobile radiator comprising two header members and a set of radiator pipes to connect the header members. for the circulating medium, the header members having associated therewith yielding elements to form the sole contacting supports for the radiator pipes and means to hold said elements in tight frictional supporting contact with the. pipes and also to seal the header member over the area surrounding the open ends of the several pipes.
